How to solve Chinese garbled code in linux python?

Solution to Chinese garbled code in python under linux

1. Scenario description

linux server Anaconda3 was installed and Pyhton's K-means algorithm was executed. The result was garbled Chinese characters as shown below. It was solved last time, but I forgot to record the solution process. This time I configured a new server, and it appeared again. If it is not configured by default, matplotlib will draw garbled characters. This time I will record the solution process, hoping to help myself and those in need. friend.

2. Solution

There are several solutions on the Internet. I only introduce the ones that are feasible in practice.

1. Check the matplotlib font location

python
import matplotlib 
print(matplotlib.matplotlib_fname())

#记录下来，字体位置我的是：/home/ruanjianlaowang/anaconda3/lib/python3.7/site-packages/matplotlib/mpl-data/matplotlibrc

exit()

2. Upload the font to the server

cd /home/ruanjianlaowang/anaconda3/lib/python3.7/site-packages/matplotlib/mpl-data/fonts/ttf

通过ftp或者其他方式，将字体传上去，我们传的是：simhei.ttf

3. Delete Font cache

cd  ~/.cache/matplotlib
rm -rf *

4. Restart the python application

nohup python k-means.py &

Note: If it doesn’t take effect, try changing the configuration file again . (We haven’t changed this configuration file before, but an episode happened this time. The jmeter test we used this time was still garbled. Later we changed it and it still didn’t work. It turned out to be a problem with jmeter)

cd  /home/ruanjianlaowang/anaconda3/lib/python3.7/site-packages/matplotlib/mpl-data

vi matplotlibrc 
font.family         : sans-serif  #去掉前面的#
font.serif          : simhei, DejaVu Serif,   #新加了simhei

Interlude

This time I used jmeter to test it and found that it was still garbled after all changes. Later, utf-8 parameters were added to the jmeter request.
